Which is a characteristic of an amorphous solid? 1. made up of crystals 2. particles arranged in a repeating pattern 3. has a distinct melting point 4. becomes softer as temperature rises

4. becomes softer as temperature rises

An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
